POWER TRANSMISSION.

Application filedl'anuary 24, 1914. Serial No. 814,055.

To all whom it may %067'1" Be it known that I, GEORGE G. MILNE, a citizen of the United States, and a resident of Rye, county of Westchester, and State of New York, have invented certain new and useful Improvements in Power Transmission, of which the following is a specification.

My invention relates to improvements in power transmission, and more particularly to driving connections between a car axle and dynamo electric machine and where the axle drives the dynamo, although certain of my improvements will be found advantageous where the parts are reversed.

One object of the invention is to provide a resilient connection in the driving means whereby when the car is suddenly and rapidly started the strain on the rotating arts. will be relieved and Breakage of the s afting prevented.

A further object of the invention is to provide a simple and eficient apparatus for this purpose which has a part which is constructed and adapted to give way or break in case the driven part is stopped for any reason while the driving part continues to rotate, so that damage will not be done to the shafting and there is no likelihood that the shafting or other parts will become broken and drop to the tracks so as to be apt to derail the car or train and cause serious accident. shaft-drive for such purpose has been that, in case the dynamo should become stopped because of a hot box in its armature bearing, its burning out or a breaking of any of its parts, or because of the car being suddenly started, there was great likelihood of the shafting connecting it with the-car axle breaking, causing part of the shafting to drop to the tracks, which would likely cause derailment. Hence the belt-drive has may be made in the particular apparatus One disadvantage of the Specification of Letters Patent.

shown and described without departing from the spirit and scope of my invention 1n 1ts broader aspects, hence I do not desire to be llmited to the details shown and described but desire to cover allforms coming within the scope of the appended claims.

In the drawings, Figure 1 is a side elevation illustrating the application of my invention in one form; Fig. 2 is an enlarged detail of the driving means adapted to give way and adjacent parts; Fig. 3 is a section taken on the line 33 ,of Fig. 2; Big. 4 is a view similar to Fig. 2 but showing a modification; and Fig.5 is a section taken on the line 55 of Fig. 4.

Referring to Figs. 1 to 3, 6 represents a car body provided at one end with a truck 7 and with wheels 8 rigid with the axle 9. A. casing 10 issupported by the axle 9 and, links 11 hanging from an arm 12 carried by theend sill 13 of the truck. The casing 10 contains any suitable driving gears receivingmotion from the axle 9 and driving the shafting 14 through a universal joint 15-. Fixedly supported from the .car body by a frame 16 is a dynamo electric machine 17,

although the dynamo .may be supported from the truck if desired. The rotating armatureof the dynamo carries at one end rigidly secured thereto a member 18 having projecting horizontally therefrom a resilient 'etallic' member 19 adapted to be engaged by a lateral pin 20 extending from the shaft 21 which shaft 21 is adapted to slide in the direction of its axis in the bearings 22 rigid with or forming part of the dynamo frame. The shaft 21 is connected ,with the shafting 14 by a universal connecs tion. at 23. The member 19 is made sufliciently stiff so that as thegcar starts up itv will gradually bring the dynamo up to speed and drivethe same by being driven by the pin 20. In case, however, the dynamo should become stopped as=bymeans of a hotel. or

box in the dynamo or breakage of partswhile the car is still moving and its axle driving the shafting 14, etc., the member 19- will bend sufliciently to allow the pin 20 to pass by it. The pin 20 continues to revolve, bending and passing the member 19 at each revolution until the car stops or the member breaks off because of the vibrations and jars to which it is subjected. The member 19 is thus made sutficiently weaka so that such stoppage of the dynamo will not cause breakage of the shafting labor other'parts,

I vent breakage.

and if the car is suddenly rapidly started or stopped the resilient member will relieve the strain on the rotating parts and thus pre- When going about curves, and if for any other reason the distance between the bearing 22 and the casing 10 varies, the shaft 21 will slide through the bearing 22 and the member 19' is long enough so that the pin 20 will at the same time slide along it and it will always engage the pin 20 under such varying conditions.

Referring to Figs. 4 and 5, in the modification there shown'the resilient member 19 instead of being secured to the member 18 on the dynamo armature, is secured to the pin- 20 and works in a slot 24 in the disk member 18, and in case the dynamo is stopped when the car is running the member 19.will bend and slip out of the slot and merely wipe around over the flat face of the disk member 18. When, however, the apparatus is, started up anew, if the dynamo be in order, the member 19 as it now moves slowly over the .face of the disk 18 will, when it first reaches the slot 24, slip into it, and then start up the dynamo in the regular way. Other forms of spring'or resilient connections may obviously be used, and in some cases the spring or resilient connection may be fixedly secured at both its ends to the connecting parts.
